When it is seen - When it occurs; that is, when Moab actually "becomes" weary.

Is weary on the high place - The "high place" denotes the place of idolatrous worship, and here means the same as the temple of Chemosh or his sanctuary. Temples and altars were usually constructed on such places, and especially the temples of the pagan gods. Moab is represented here as looking to her gods for protection. Weary, exhausted, worn down with calamities, she is represented as fleeing from the desolate towns and cities, and taking refuge at the altar, and seeking assistance there. This, says Jerome, is the final misery. She is now forsaken of those aids to which she had always trusted, and on which she had relied. Her people slain; her towns destroyed; her strong places broken down; her once fertile fields languishing and desolate, she flees to the shrine of her god, and finds even her god unable to aid and defend her.

Shall come to his sanctuary - To his "principle" sanctuary; or to the temple of the principal god which they worshipped - the god "Chemosh" 1 Kings 11:7. This does not mean the temple at Jerusalem, though Kimchi so understands it; but the temple of the chief divinity of Moab. Jerome says that this temple was on mount Nebo.

Shall not prevail - That is, her prayer shall not be heard.

When it is seen that Moab, etc. "When Moab shall see," etc. - For נראה nirah, a MS. reads ראה raah, and so the Syriac and Chaldee. "Perhaps כי נראה ki nirah is only a various reading of כי נלאה ki nilah." Secker. A very probable conjecture.

And it shall come to pass, when it is seen that Moab is weary on the high place,.... With weeping there, Isaiah 15:2 or with frequent sacrifices, and going from one high place to another, as Balak king of Moab did; and by comparing places together, it looks as if this was the way of the Moabites in their distress, to offer up a multitude of sacrifices in different places; now, when it should be seen by others, and appear to themselves, that they wearied themselves in vain, and all their cries and sacrifices were to no purpose, they should then be ashamed of them, leave off, and betake themselves to some other method; though Jarchi interprets it of their being weary of fighting on the high places of their towers, which when observed, they would take another course, and apply to devotion:

that he shall come to his sanctuary to pray; to the temple of Chemosh, and to pray to that idol to help him, 1 Kings 11:7,

but he shall not prevail; his prayers shall be ineffectual; his suit will be fruitless, and without success; or "he cannot", that is, his idol cannot help him. So Kimchi interprets his sanctuary of the house of his God; and the Targum, of the house of his idolatry; yet since the house or temple of an idol is never called a sanctuary, it may be understood of God's sanctuary, the temple at Jerusalem; and the sense be, that when Moab shall see that his praying and sacrificing to idols are in vain, and he has tired himself with his superstition and idolatry, without having any redress, he shall think and express his desire of going up to the temple of Jerusalem, and of praying to the God of Israel; but he shall not be able to do it, because of the enemy; and could he get thither, he would not prevail with God, for the decree was gone forth, which could not be frustrated, as follows. Ben Melech interprets it of the palace of the king.

The ultimate reason for this restlessness is, that Moab does not know the living God. "And it will come to pass, when it is seen that Moab is weary with weeping upon the mountain height, and enters into its sanctuary to pray, it will not gain anything." נלאה נראה, a pictorial assonance, such as Isaiah delights in. נראה .ni st is transferred from the Israelitish worship (appearance before God in His temple) to the heathen; syntactically, si apparuerit, etc., with Vav before the apodosis. It would be with the Moabites as with the priests of Baal in the time of Elijah (1 Kings 18:26.).

And it shall come to pass, when it is seen that Moab is weary on the high place, that he shall come to his {n} sanctuary to pray; but he shall not prevail.

(n) They will use all means to seek help for their idols, and all in vain: for Chemosh their great god will not be able to help them.

16:12 When - When it shall appear that all their other devotions are vain. His sanctuary - To the temple of his great god Chemosh. But - His god can neither hear nor help him.

12. when it is seen that-rather, "When Moab shall have appeared (before his gods; compare Ex 23:15), when he is weary (that is, when he shall have fatigued himself with observing burdensome rites; 1Ki 18:26, &c.), on the high place (compare Isa 15:2), and shall come to his sanctuary (of the idol Chemosh on Mount Nebo) to pray, he shall not prevail"; he shall effect nothing by his prayers [Maurer].

16:6-14 Those who will not be counselled, cannot be helped. More souls are ruined by pride than by any other sin whatever. Also, the very proud are commonly very passionate. With lies many seek to gain the gratification of pride and passion, but they shall not compass proud and angry projects. Moab was famous for fields and vineyards; but they shall be laid waste by the invading army. God can soon turn laughter into mourning, and joy into heaviness. In God let us always rejoice with holy triumph; in earthly things let us always rejoice with holy trembling. The prophet looks with concern on the desolations of such a pleasant country; it causes inward grief. The false gods of Moab are unable to help; and the God of Israel, the only true God, can and will make good what he has spoken. Let Moab know her ruin is very near, and prepare. The most awful declarations of Divine wrath, discover the way of escape to those who take warning. There is no escape, but by submission to the Son of David, and devoting ourselves to him. And, at length, when the appointed time comes, all the glory, prosperity, and multitude of the wicked shall perish.
